keep an eye out for an L26, grab the crank and rods (basicly a stroker kit!)
find an L28e intake manifold (flows better than the L20et, simpler too)
find a L24e
( cheap as chips, find another wreck R30, series 1 has E88 head, better for turbo)
rebuilt VG30 turbo, pretty much the size matching is the hard part.
Kelford Cams in NZ have some good turbo grinds, like a 256 duration turbo grind, free shipping to Aus too.
Hose tail injectors, VL turbo are 270cc or so, L28et same, just harder to find.
KA24e Throttle body, in the Ti fwd Pintara, efi 2.4 navara, ford corsair ghia 2.4 (ita 60mm DIA)
a throttle body space is required to keep the stock linkages. im looking at converting to cable though
